MRI-guided Ultrasound for Tremors Gains FDA Approval

The FDA approved InSightec’s focused ultrasound device to treat essential tremors in patients who have not responded to medication.

ExAblate Neuro uses magnetic resonance images to deliver focused ultrasound to destroy brain tissue in a tiny area thought to be responsible for causing tremors.

The condition is also treated with beta blockers or anticonvulsants, and when medications fail to control symptoms, essential tremor can be treated with surgery or a deep brain stimulation device.
